GASOLENE-PURIFIEB.

Specification of Letters Patent.

Patented May 3, 1921.

Application filed December 3, 1919. Serial No. 842,049.

To all whom it may concern..- v

Be it known that I, HUGH ALLEN DEEKS a subject of the King of Great Britain, and a resident of Moose Jaw, in the Province of Saskatchewan and Dominion of Canada, have invented certain new and useful Improvements in Gasolene-Purifiers, of which the following is a specification.

My invention is an improvement in gasolene purifiers, and has for its object to provide a simple, inexpensive device of the character specified adapted to be arranged between the fuel tank and the carburetor of an internal combustion engine, for thoroughly removing all impurities from the fuel before it is admitted to the carbureter. A further object of the invention is to construct the purifier so that the screening elements will be self cleaning and such that the accumulating foreign material can be readily drawn off from time to time.

In the drawings:

Figure l is a vertical section of the improved purifier;

Fig. 2 is a section at right angles to Fig. 1.

In the present embodiment of the invention a suitable casing l is provided, of cylindrical form, having connected therewith a bracket plate 2, which permits the purifier to be connected to a fixed support at the proper point between the fuel tank and the 1 carbureter. The casing l is to be supported with its axis horizontal, and it is provided at the center of one head with an outlet nipple 3 and near its top in the other head with an inlet nipple 4.

A drain valve 5 is connected with the casing at the under side thereof, this casing being designed to permit the impurities and sediment to be drained from the tank. A suitable filter is arranged transversely of the casing between-the inlet and the outlet, and between the drain valve and the outlet, and the said filter comprises a ring 6 which is tapering in form and which carries at its large end a screen 7 of perforate material of suitable mesh.

The small end of the ring 6 has an outwardly bent flange 8, and at this end of the ring there is arranged a partition or diaphragm 9 of chamois. The edges of the chamois are bent around the flange 8 and are clamped to the ring behind the flange, by a ring 9 of wire or the like, the said rlng being tightly clamped upon the mug 6 and upon the chamois.

In use, the fuel to be purified enters the casing through the inlet nipple 4:. As it passes through the screen 7 of wire gauze the coarse impurities will be removed and will be thrown down upon the bottom of the casing 1. The chamois will separate all the partlcles not entirely in solution, leavin that portion of the fuel which passes beyond the chamols pure and suitable for use. When sediment collects in the bottom of the casing it may be drawn off through the valve 5. It will be noticed that there is a recess at the bottom of the casing at the valve 5 and encircling the said valve.

The large end of the ring 6 is secured to the interior of the casing in any suitable manner, as, for instance, by brazing or soldering, and 1t will be noticed that the plane of the ring is inclined, the upper portion of the ring and the upper portions of the partitions 7 and 9 being nearer the inlet end of the casing than the lower ends of the sand ring and partition.

Further it is to be observed that the collar is tilted slightly so that the screen and chamois diaphragm take a slightly inclined position within the casing as shown.

Owing to the fact that the screen and chamols are in approximately an upright positlon, there is a natural tendency for the foreign material caught by them to gradually work down toward the bottom and here such material is directed-toward the recess by the flaring shape of the collar.

The slightly tilted position given the screen and chamois has also a tendency to keep them clean as considerable of the material arrested by them can sink directly down to the bottom of the caslng.

Further I have found that by placing the screen and chamois in a more or less upright position that the vibration of an automobile when it is in use, has the effect of vibrating the screen and chamois and the vibratory movement taking place as it does in a liquid has a natural tendency to Wash the screen and chamois and deposit the sediment in the bottom of the casing where it collects in the recess and from which it can be drawn as occasion may demand.

I claim:

1. A device of the character specified, comprising a substantially cylindrical casing having an inlet in one end and an outlet in the other, a tapered ring inserted into such casing, the larger end of the ring fac- ,ing the inlet end of the casing, a gauze screen suitably secured to the larger end of the ring and a chamois diaphragm suitably secured to the smaller end of the ring.

2. A device of the character specified comprising a substantially cylindrical casing having an inlet in one end and an outlet in the other, and filtering means comprising a partition of gauze and a partition of cham- 10 ois arranged between the inlet and the outlet and extending transversely of the casing and spaced apart from each other, a tapering ring having its large end secured transversely of the casing and having the gauze connected With the said end. and the chamois connected With the small end, the partitions inclining toward that end of the cats ing provided with the inlet at their upper ends.
